Problems solved by technology

[0004] Because the existing blood collection test tube racks cannot distinguish the order of the blood collection test tubes, many medical staff put the blood collection test tubes into the plate when collecting blood, and did not strictly follow the blood collection order. Blood collection personnel may also mix up the order, making follow-up test results inaccurate and increasing the difficulty of diagnosis and treatment for doctors

Embodiment 1

[0027] refer to figure 1 , image 3 As shown, a blood collection test tube slot device, the test tube slot device has a plurality of slots 1 for storing blood collection test tubes 8, the slots 1 include a groove wall 101 and a test tube base 102, and a limit spring 2 is installed below the test tube base 102 An electric lifting device 3 is installed below the limit spring 2, and the electric lifting device 3 can include a connection plate 301 connected to the limit spring 2 and a coil winding arranged below the connection plate 301. Repelled magnet 302, conductive sheet 103 is installed on the test tube base 102, and a pair of first electrode sheets 5 and a pair of second electrode sheets at a predetermined distance matched with the conductive sheet 103 are installed on the groove wall 101 of the slot 1 6. One of the two first electrode pieces 5 is connected to the positive pole of the power supply device 15 through a wire 4, and the other first electrode piece 5 is connecte...

Embodiment 2

[0031] refer to Figure 4 , Figure 5As shown, Embodiment 2 of the present invention is basically the same as Embodiment 1, the only difference is that a clamping portion 11 is provided in the slot 1 in Embodiment 2 to replace the alarm device 9, when the previous sequence of blood collection After the test tube 8 is taken away, the clamping part 11 releases the next sequential blood collection test tube 8 . Specifically: a compression spring 12 is provided between the clamping portion 11 and the slot 1, the clamping portion 11 clamps the blood collection test tube 8 under the action of the compression spring 12, and a limit spring 2 is installed below the test tube base 102, and the limit spring 2 The support plate 14 fixed to the groove wall 101 is installed below, and the coil winding is installed in the placement groove below the support plate 14. Conductive sheet 103, a pair of second electrode sheets 6 that cooperate with conductive sheet 103 are installed in the slot ...

Embodiment 3

[0033] refer to Figure 6 As shown, Embodiment 3 of the present invention is basically the same as Embodiment 1 and Embodiment 2, the only difference being that a pop-up device 13 is provided in the slot 1 in Embodiment 3, and the length of the test tube is not greater than that of the slot. 1, when the tubes are taken according to the predetermined blood collection sequence, the blood collection test tube 8 is ejected by the pop-up device 13, and the test tubes that have not been ejected cannot be taken out. Limiting spring 2 is installed below 102, and pop-up device 13 comprises connecting plate 301 that is connected with limiting spring 2 and is located at the coil winding below connecting plate 301, and magnet 302 is installed on connecting plate 301, and conductive sheet is installed on test tube base 102 103, the slot wall 101 of the slot 1 is equipped with a pair of second electrode sheets 6 that cooperate with the conductive sheet 103, any one of the second electrode s...

Abstract

The invention relates to a blood sampling test tube slot device which is provided with slots for storing blood sampling test tubes. The slot device has at least two states including a normal state in which the blood sampling test tubes can be taken in an expected mode and an abnormal state in which the blood sampling test tubes can be taken in an unexpected mode. The normal state and the abnormal state are used for distinguishing whether the blood sampling sequence is correct or not. In clinical blood sampling, substances such as an anticoagulant are added into part of blood sampling test tubes, and blood sampling should be carried out in a certain sequence according to related standards. In practical application, medical staff often do not carry out blood sampling according to a preset blood sampling sequence due to objective causes or subjective understanding. The blood sampling test tube slots have at least two states for identifying whether the blood sampling sequence is correct or not, and the blood sampling test tubes can be ensured to sample blood according to an expected sequence through a fool-proof mechanism in a manner that the blood sampling test tubes cannot be taken out when the blood sampling sequence is incorrect.

Description

technical field [0001] The invention relates to a blood collection test tube slot device. Background technique [0002] In modern medical diagnosis, blood testing is the basis for widely used medical diagnostic methods and physical function examinations. Blood testing is a very important auxiliary diagnostic tool. Doctors use the test results to judge the patient's condition and lesions. Therefore, standardized During the blood collection process, accurate and accurate blood test results are an important prerequisite for correct and efficient diagnosis and treatment by doctors. [0003] There are many items for blood testing, such as liver function, blood routine, blood sugar, etc. According to different diagnostic purposes, one test may involve many different testing items, and multiple blood collection tubes are required for blood collection. In some testing items, different additives are added to the blood collection test tubes, such as anticoagulant, coagulant, etc., wh...
